Clean iPhone cache after iOS 8.3

I was a PhoneClean and PhoneExpander user but, after iOS 8.3 update, they (and similar apps) stopped working due to some modifications in iOS.

Now I start having too much cache on my phone but I don't want to remove and reinstall apps to clean their cache, is there a faster way to do that? (apps updated to support iOS 8.3 or iOS apps or other ways...)

I don't want to jailbreak.
